Unable to open PDFs in SharePoint Online

[laurah14081032]

We have run into issues opening some PDF files from SharePoint Online when using Chrome (see screenshot).  We have the Adobe Document Cloud add in installed in our tenant.  The PDFs in question can be opened in the browser without Adobe Document Cloud in Edge and by clicking Open > Open in browser while in the document library using Chrome.  The PDFs in question can also be opened by Adobe Reader after downloading the PDF from the document library.  Is this a known issue?  Is there something we can do to the PDFs to fix the issue?  Or is the only work around to open the PDF in the browser or download it and open in Adobe Reader?

Hi @kcdc-phill ,

Sorry for the inconvenience caused !!

Adobe Document Cloud is an SPOD Integration App over the web. Though, it has most of the features like Desktop Adobe Reader but still there are few which are keep on adding. So, in anyway bother are not exactly the same in terms of features as well as rendering complex and special formatted PDFs.

In your case, I believe this is specific to your PDF type and Unfortunately since the PDF can't be shared with us,we are unable to provide you the exact findings for the same.

For more info, I'd appreciate you reach out to our Support or email us at ecs[at]adobe[dot]com

Regards,
Rahul

Hi @Rahul5E6F 

Thank you for the reply

We followed your advise and sent an email to ecs[at]adobe[dot]com

Hoping they will reply fast and be able to assist

We now have a PDF which is not confidential and I can share it

Is there anyway to send you that as DM instead uploading it here so you can analyze and provide more feedback?

Thanks

KCDC

Hi @kcdc-phill 

We have the exact same issue as you describe with the SPOD integration.

File works perfectly fine when opening in Microsoft Edge PDF viewer and when cdownload and open in desktop app.

I found out that my file had the same issue when I downloaded it and uploaded to my Adobe Document Cloud, so not dependent on the SPOD integartion, seems like a Adobe Document Cloud issue.

Same process as you described, we scan files to PDF -> SPO and use Document Cloud integration.

Tried to remove/reinstall

It's random files and random users, some files is perfectly fine and others uploaded just a couple of minutes later have the issue.

We are having the same issue. Started out intermittent, now it's down completely. All users, all browsers. Opened a ticket with Microsoft with the following information from Chrome console. They said it is an Adobe issue and provided link to this post.

Yes, this is Microsoft related issue and we already following up with the MS support.
I'd request you to wait unti we get any fix from MS on this.

Greetings,

Yes, it is resolved. MS told me several times it was on Adobe side. I knew it was on MS side. They denied. Glad it is fixed!

Hi Ross,

Thank you for reaching out and sorry for the delay in response.

Would you mind elaborating on the issue you are currently experiencing?

Please let us know about the Adobe service you are using so we can provide you with the right information.

Let us know if the issue is already resolved.

Thanks,

Meenakshi

Also experiencing this issue on our M365 tenant:

The document was "Checked out" for editing in our document library. I noticed when the document was "Checked In", the document was able to open correctly without the error.

Does document cloud not support checked out documents then?

[Eric987]

Same issue here, it appears Adobe document cloud error "You may not have permission to access the SharePoint file being used in this workflow." occurs when Content Approval is enabled and file is either in Draft or Pending state, although no error for the user who uploaded file, another User may workaround the issue by either Check out or Publishing the file.

Hello @kcdc-phill 

I have same error but different issue. I found out that we had % in folder name in Sharepoint Online. After removed the % it worked.

Is there a known issue of that?
